How to use it?

Package Com.test;import Java.net.malformedurlexception;import Java.net.url;import java.util.logging.level;import Java.util.logging.logger;public class test{public    static void Main (string[] args) {        try {            //create a URL instance            URL baidu=new url ("http://www.baidu.com");            URL url=new url (Baidu, "/index.html?username=wonderq#test");            SYSTEM.OUT.PRINTLN ("agreement:" +url.getprotocol ());            System.out.println ("Host:" +url.gethost ());            If no port number is specified, the default port number is used, at which point the Getport return value is 1            System.out.println ("Port number:" +url.getport ());            System.out.println ("File path:" +url.getpath ());            System.out.println ("file name;") +url.getfile ());            SYSTEM.OUT.PRINTLN ("Relative Path:" +url.getref ());            System.out.println ("Query string:" +url.getquery ());        } catch (Malformedurlexception ex) {            Logger.getlogger (Test.class.getName ()). log (Level.severe, NULL, ex);}}}     

Output Result:

Run
Protocol: HTTP
Host: www.baidu.com
Port number: 1
File path:/index.html
The name of the file;/index.html?username=wonderq
Relative path: Test
Query string: USERNAME=WONDERQ

Test procedure:

Package Com.test;import Java.io.bufferedreader;import Java.io.ioexception;import java.io.inputstream;import Java.io.inputstreamreader;import Java.net.malformedurlexception;import Java.net.url;import        Java.util.logging.level;import Java.util.logging.logger;public class test{public static void Main (string[] args) {            try {//Create URL instance url url=new url ("http://www.baidu.com");            The OpenStream () method of the URL gets the byte input stream of the resource represented by the object InputStream Is=url.openstream ();            Converts the byte input into a character input stream InputStreamReader isr=new InputStreamReader (IS, "utf-8");            Add buffer BufferedReader br=new BufferedReader (ISR) for character input stream;            Defines a string to hold the read data string data= br.readline ();                while (Data!=null) {System.out.println (data);            Data=br.readline ();            } br.close ();            Isr.close ();        Is.close (); } catch (Malformedurlexception ex) {Logger.getlogger (teSt.class.getName ()). log (Level.severe, NULL, ex);        } catch (IOException ex) {Logger.getlogger (Test.class.getName ()). log (Level.severe, NULL, ex); }     }}

Output Result:

Save the above results in one text and change the suffix named. html. Then double-click the text.
